# Using Mixed Electromagnetic Boundary Conditions!

Hi
As we know, we have two kinds of Electromagnetic Boundary Conditions for interfaces in an electromagnetic problem.one is imposing the continuity of Bz and Hr and the other is applying the continuity of A(Magnetic Vector Potential) and the discontinuity of its derivative with respect to the normal direction.
Well,my question is :
Can we use a mixture of these two boundary conditions in one problem?
Imagine we have 5 interfaces in our problem.Are we allowed to use the first series for 3 interfaces and use the second ones for the rest?
